BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a seat equipped with an electric / electronic device, in which an accessory is assembled to a seat pad together with a device body of an electric or electronic device, and the seat pad is covered with a trim cover.
[0002]
[Prior art]
Conventionally, a sheet heater can be used as an electrical or electronic equipment equipment sheet. The seat heater is configured so that the heater body is disposed on the seat surface of the seat pad, and an attached part such as a thermostat is assembled to the recessed portion of the seat pad to alleviate the sense of protrusion.
[0003]
However, in the heater-equipped seat, the seat pad is covered with a trim cover formed by laminating the skin material and the wadding material with the thermostat and other attached parts assembled in the recess, but the wadding material of the trim cover is sufficiently thick. Otherwise, it feels strange due to the recess. In addition, if the recesses are relatively wide and large, the wading material will bend into the recesses and become depressed, so that it feels strange, so the assembly site is limited to parts that are hard to feel the human body Is done.
[0004]
[Problems to be solved by the invention]
The present invention prevents a sense of incongruity from being felt even when an electric or electronic device accessory is assembled to a seat pad, and restricts the range of electric or electronic device installation, the location, or the wadding thickness. The purpose is to provide an electrical / electronic equipment equipment sheet that is not received.
[0005]
[Means for Solving the Problems]
In the electric / electronic equipment equipment sheet according to the present invention, the electrical or electronic equipment accessory is assembled into the interior of the accommodation space formed stepped down from the seat pad surface of the seat pad, and covers the accommodation space of the accessory The tape is bonded to the seat portion surface of the seat pad, and the space portion is retained by a non-woven tape.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the accompanying drawings, the illustrated embodiment includes a planar antenna 1 on a seating surface of a seat back 2 as shown in FIG. In preparation for the situation, it is equipped with a system mechanism that detects the presence or absence of a passenger, whether the passenger is an adult or a child, etc. The vehicle seat is illustrated.
[0007]
As shown in FIG. 2, the planar antenna 1 is obtained by integrating an antenna body 10 for sensing capacitance with an antenna base fabric 11, and is used for a bank 1a to a seat upper part, a lower part of the seat surface, and a side of the vehicle body. It is divided into 1c. The planar antenna 1 includes a harness 13 and a coupler 14 that are led out from a terminal 12 of the antenna body 10 as accessory parts. The planar antenna 1 is mounted on the seat pad 20 of the seat back 2 by mounting the antenna body 10 on the seat surface and assembling the harness 13 from the terminal 12 into the accommodation space provided on the seat surface.
[0008]
As shown in FIGS. 3 and 4, the seat pad 20 is provided with accommodation spaces 20 a to 20 c that are stepped down from the seat surface. The accommodation spaces 20 a to 20 c may be formed in accordance with a shape in which the harness 13 can be assembled from the terminal 12 of the planar antenna 1. For example, with respect to the planar antennas 1a and 1b for the upper and lower seat surfaces, a vertically long concave is provided on the seat surface near the critical portion with the bank, and the planar antenna 1c on the bank side. On the other hand, a rectangular flat can be provided so as to extend over the hanging groove 20d of the trim cover. In the accommodation spaces 20a to 20c, through holes 20e are provided on the inner bottom surface for drawing the coupler 14 including the harness 13 to the back side of the seat pad 2.
[0009]
In order to cover the accommodation spaces 20a to 20c with the attached parts assembled, non-woven fabric tapes 21a to 21c with less elongation are provided as shown in FIG. The nonwoven fabric tapes 21 a to 21 c are formed so as to be able to retain the shape of the space by covering the accommodation spaces 20 a to 20 c and bonding them to the seat surface of the seat pad 20.
[0010]
In addition to the nonwoven fabric tapes 21a to 21c, in order to provide the planar antenna 1 between layers of a wadding material such as a urethane slab that forms a trim cover, the wadding materials 22a to 22c corresponding to the area provided with the planar antenna 1 are skin materials. It is provided in a separate member separately from the normal thickness of the wadding material. The wadding members 22a to 22c are bonded to the seat surface of the seat pad 20, and the upper and lower seat surfaces of the individually formed planar antenna 1 and the banks 1a to 1c on the side of the vehicle body are bonded. It has a fixed area.
[0011]
The wadding materials 22a to 22c may divide a corresponding portion into approximately equal thicknesses from a wadding material having a thickness of about 12 mm that is laminated with a skin material. Preferably, the laminating side with the skin material may be formed thin by increasing the thickness of the wadding materials 22a to 22c to which the planar antenna 1 is bonded.
[0012]
In the illustrated embodiment, except for the thickness of the planar antenna 1, the laminating side with the skin material is bonded to the planar antenna 1 so that the distance to the seat surface of the planar antenna 1 is about 3 mm. The materials 22a to 22c are formed to a thickness of about 8 mm capable of maintaining the form. This thickness setting is in the area equivalent area including the planar antenna 1 described above, and the wadding material on the general surface is about 12 mm thick as usual, and the portions corresponding to the respective wadding materials 22a to 22c are within the area of the general surface. What is necessary is just to form as a thin wadding layer by denting and forming in a concave shape.
[0013]
In order to attach the planar antenna 1 (1a to 1c) to the seat pad 20 from each part, the antenna body 10 is bonded to the front side of the wadding materials 22a to 22c with the antenna base cloth 11, as shown in FIG. In addition, the wadding materials 22a to 22c are bonded and fixed to the seat surface of the seat pad 20. As a result, the planar antenna 1 (1a to 1c) can be easily provided by aligning with high accuracy on the seat back surface of the seat back 2 or the seat pad 20.
[0014]
As shown in FIGS. 7 and 8, the harness 13 of the planar antenna 1 (1a to 1c) is bent from the terminal 12 and is provided in a critical space between the seat surface of the seat pad 20 and the bank surface. (Only the bank side is shown) The assembly and coupler may be connected to the external wiring by pulling out from the through hole 20d provided on the inner bottom surface of the accommodation space to the back side of the seat pad 20. After the harness 13 is assembled from the terminal 12, the non-woven tape 21c covering the housing space 20c by sandwiching the bent portion of the antenna body 10 is bonded to the seat surface of the seat pad 20 to retain the space portion. To do.
[0015]
When the seat cover 20 is covered with a trim cover 23 as shown in FIG. 9, the trim cover 23 is formed by integrally laminating a general surface of a padding material including a thin padding layer 23a inside the skin material 23b. Thus, by combining the thin wading layer 23a and the wadding material 22c with the planar antenna 1 interposed between the layers, the entire wadding material of the trim cover 23 including the general surface can be maintained at a uniform thickness. Since the nonwoven fabric tape 21c is made of a thin material with little elongation, the thickness of the trim cover 23 is not affected.
[0016]
In the seat with the occupant detection antenna configured as described above, the non-woven fabric tapes 21a to 21c that are less stretched are attached to the seat surface of the seat pad 20, thereby covering the accommodation spaces 20a to 20c for assembling the harness 13 from the terminal 12. The said space part can be shape-retained with the nonwoven fabric tapes 21a-21c. For this reason, it is possible to prevent a sense of incongruity from being felt even when an electric or electronic device accessory is assembled to the seat pad 20, and restrictions on the electric or electronic device assembling range, part, or wading thickness. Not receive.
[0017]
In addition, the planar antenna 1 can keep the antenna output good because the mounting position can be brought close to the seat surface by interposing at least a normal thickness of the wading material between the two layers 22a to 22c. Can do. Further, since the seating surface portion is formed by the trim cover 23 made of the wadding material that keeps the entire surface including the general surface with a uniform thickness, a seating feeling equivalent to that without attaching the antenna can be obtained.
[0018]
【The invention's effect】
As described above, according to the electric / electronic device equipment seat according to claim 1 of the present invention, the electric or electronic device accessory part is assembled in the interior of the housing space formed stepped down from the seat pad surface. By attaching a non-woven tape covering the accommodation space of the accessory part to the seat part surface of the seat pad and retaining the space part with the non-woven tape, the unnaturalness due to the accommodation space for assembling the accessory part of the electric or electronic device It is possible to prevent a feeling of feeling and to obtain a seating feeling equivalent to that without attaching an electrical or electronic device accessory.
